And Not Or

Released in 1982 as an instrumental companion to the vocal-led 'For To Next', 'And Not Or' marks Steve Hillage's definitive transition from the psychedelic space rock of the 1970s into the electronic and ambient territories that would define his later career. The album's title and aesthetic are deeply influenced by the early home computing revolution, specifically the logical operators of the BASIC programming language. Recorded primarily with synthesizers and drum machines, the album features Hillage's iconic glissando guitar technique - a style of playing using a slide to create smooth, ethereal pitch shifts - recontextualized within a digital framework. While 'For To Next' flirted with synth-pop song structures, 'And Not Or' leans into long-form instrumental exploration. It is historically significant as a foundational text for the UK's ambient house scene, directly influencing the chill-out room aesthetics of the early 90s. Critics often cite this pair of albums as the point where Hillage successfully modernized his sound without losing his cosmic identity.
